5. Tree Topology:

T ree topology is a computer network topology in which all the nodes are directly or indirectly connected to the main bus cable. Tree topology is a combination of Bus and Star topology.
In a tree topology, the whole network is divided into segments, which can be easily managed and maintained. There is a main hub and all the other sub-hubs are connected to each other in this topology.
Following are the advantages of Tree topology:

1. 
   Large distance network coverage.
   
2. 
   Fault finding is easy by checking each hierarchy.
   
3. 
   Least or no data loss.
   
4. 
   A Large number of nodes can be connected directly or indirectly.
   
5. 
   Other hierarchical networks are not affected if one of them fails.
   

Following are the disadvantages of Tree topology:

1. 
   Cabling and hardware cost is high.
   
2. 
   Complex to implement.
   
3. 
   Hub cabling is also required.
   
4. 
   A large network using tree topology is hard to manage.
   
5. 
   It requires very high maintenance.
   
6. 
   If the main bus fails, the network will fail.
   

6. Hybrid Topology:

A Hybrid topology is a computer topology which is a combination of two or more topologies. In practical use, they are the most widely used.
I n this topology, all topologies are interconnected according to the needs to form a hybrid. All the good features of each topology can be used to make an efficient hybrid topology.
Following are the advantages of Hybrid topology:

1. 
   It can handle a large volume of nodes.
   
2. 
   It provides flexibility to modify the network according to our needs.
   
3. 
   Very Reliable(if one node fails it will not affect the whole network).
   

Following are the disadvantages of Hybrid topology:

1. 
   Complex design.
   
2. 
   Expensive to implement.
   
3. 
   Multi-Station Access Unit(MSAL) required.
